1-Phase Electric Motor 5.5kW 7.5Hp

The 1-Phase Electric Motor 5.5kW 7.5Hp is a compact electric motor line designed for easy installation and integration into various applications. This electric motor is highly rated for its stable, durable performance and superior energy-saving capability.

Exterior of the 1-Phase Electric Motor 5.5kW 7.5Hp

The 1-phase electric motor features a characteristic terminal box containing running and starting capacitors, housed together in a terminal box or positioned equidistant on the sides of the motor. The exterior of the motor has a dark green paint coating, providing high aesthetics and solid durability.

Inside, the electric motor is wound entirely with 100% pure copper wire, ensuring a powerful conversion of electrical energy into mechanical energy. This motor also comes in two common mounting styles: foot-mounted or flange-mounted, allowing users to easily choose the right installation type for their application requirements.

Internal Structure of the 1-Phase Electric Motor 5.5kW 7.5Hp

To withstand the large current of 220V 1-phase electricity at 5.5kW, the internal structure of the motor is comprehensively upgraded:

• Stator: Composed of high-quality magnetic steel sheets. The working winding and starting winding are wound with 100% pure copper wire with a very large cross-section to withstand rated currents that can reach 30A – 35A.
• Rotor: Cast steel squirrel-cage core, with a large diameter and heavy mass to generate momentum and strong starting torque right from startup.
• Capacitor System: Includes multiple large-capacity starting capacitors (to boost initial starting current) and running capacitors (to compensate for power during stable operation), usually accompanied by a centrifugal switch to disconnect the starting capacitor once the machine reaches speed.
• Bearings: Equipped with heavy-duty, high-temperature industrial bearings, ensuring the machine shaft does not run out of alignment under load.
• Cooling Fan: A large-sized fan generates strong airflow blowing along the cast iron cooling ribs

What Types of 1-Phase Electric Motor 5.5kW 7.5Hp Are Available?

• Extruders, Brick Presses, and Rice Husk Briquette Presses: Withstanding extremely large twisting and compressive forces in agricultural waste processing lines or civil building material production facilities.

Which Gearboxes Can the 1-Phase Electric Motor 5.5kW 7.5Hp Be Combined With?

With a large 38mm shaft diameter, the 1-phase 5.5kW 7.5Hp motor connects perfectly with heavy-duty gearbox lines:Cast Iron Worm Gearbox: Compatible with large WPA, WPS, WPX, and WPO models from size 120 to size 135 to create maximum pulling force for stone and cement conveyors.Aluminum Housing Worm Gearbox: NMRV series size 110 or 130, applied to equipment requiring moderate loading but lighter weight than cast iron.Heavy-Duty Helical Gearbox: R-series (inline), S-series (helical worm), or F-series (parallel shaft) models compatible with a 38mm shaft, offering the highest mechanical durability.Other transmission accessories:

• Large B-groove or C-groove pulleys, double heavy-duty sprocket chains.
• Rigid couplings, flange couplings, or large flexible couplings.

Instructions for Wiring a 1-Phase Electric Motor

Supplying power to a 3.7kW 1-phase motor requires precise operation due to the large starting current. You can watch electric motor videos beforehand to clearly understand terminal block positions.Step 1: Remove the Terminal Box CoverUse a screwdriver to remove the screws and open the capacitor box cover on the machine body. Inside are the terminal posts for the winding wires and capacitors.Step 2: Prepare Cables and Protection DevicesUse a 2-core power cable with a cross-section of 4.0mm – 6.0mm. Connect power through a 30A – 40A circuit breaker (MCB).Step 3: Connect 220V Power SupplyIdentify the 2 power supply terminals (usually marked Z1, U1 or according to the diagram printed on the box cover). Connect the 2 power wires (L and N) of 220V to these 2 terminals. Use a wrench to tighten the nuts to ensure proper electrical contact, preventing heat generation and arcing.Step 4: Operation and Rotation Direction CheckClose the cover and turn on the circuit breaker to test run. If the shaft rotates in the opposite direction of the driven machine, disconnect power and swap the positions of the two leads of the running winding (working winding).Note: If the diagram is blurred or wire ends are hard to identify, please refer to summary videos on how to measure and wire to ensure correct operation.
